#Portal turret led light update#

When the update was applied, many players launched Portal to see what it was about, and slowly discovered how it consisted in-game, then soon began to investigate the radio sound files on the Steam forums, which led to many intriguing finds.

Robins, notable voice actor for the Half-Life series, emphasized by the fact that there are 26 main sounds, which is also the total number of the alphabet letters, or a reference to the 'dinosauric' (archaic) nature of the technology used (the Morse code and SSTV technologies) compared to today's standards. The name 'dinosaur' may be a reference to the book Dinosaur Alphabet, by Harry S.

Most sounds from 'dinosaur1' to 'dinosaur26' contain a hidden image that can be viewed in an SSTV software ( Judith Mossman also hid images in her Borealis transmission, but she did not use the same system) - somewhat similar to the images seen on GLaDOS' screens at the end of Portal, the others contain Morse code (some of them also reveal voice chatter and music after clean up, possibly contained in a second layer). They include 'dinosaur1' to 'dinosaur26', used for each changed transmission, 'dinosaur_noise.wav', for when the music is scrambled, and 'dinosaur_fizzle.wav', as well as 'dinosaur_fizzle2.wav' and 'dinosaur_fizzle3.wav' (added in the Maupdate ), when the radio goes through a Material Emancipation Grill. The sounds added in the Maupdate can be found in the folder 'ambient' in the Portal sound files. The presence of these new radios seen through the Enrichment Center are likely non canonical, as they only serve the ARG. To be made in each Test Chamber, finding all radios and jamming the transmission will unlock the new Achievement, 'Transmission Received', although its description is simply '.?'. When doing so, the music will be scrambled by interferences, then Morse code or data transmission sounds will be heard, and the red sprite will turn green. In-game, the radio must each time be moved in a particular spot of the Test Chamber. The radio transmission frequency is also said to have been changed, 'to comply with federal and state spectrum management regulations', as said in the update. Playing Portal reveals that the game now has a total of 26 radios (including the ones already present before the update) playing in the Test Chambers, always in an area more or less difficult to reach (but given to the player by the music playing), and with a red sprite added to the switch. It consisted of an additional Achievement, 'Transmission Received'.
